Robert Cherry of The Plain Dealer spoke with veteran producer Rick Rubin on working with Slipknot for their latest effort, ‘Vol. 3: (The Subliminal Verses)’, due May 25th. “The thing people like about Slipknot is that it’s extreme,” Rubin said. “But extreme can be a lot of things – hard, fast, slow… So the goal is to find the extreme that most turns them on now and try to forget history. That doesn’t mean it won’t sound like Slipknot – it just means it won’t have a narrow vision.”
